3 The QS Domain Model
3.1 Assumptions for the QS Domain Model
All assumptions and business rules described in the SDTMIG QS domain are applicable to this supplement. Additional assumptions specific to the C-SSRS BASELINE are listed below.
The C-SSRS SINCE LAST VISIT is a suicidal ideation rating scale. It's a standard questionnaire administered on a CRF that is typically used in clinical trials to identify subjects at risk for suicidal ideation and behavior.
- The questionnaire is divided into 3 sections namely Suicidal Ideation, Intensity of Ideation and Suicidal Behavior.
- The first section, "SUICIDAL IDEATION", contains 5 items (QSTESTCD = "CSS0201" - "CSS0205") with QSORRES = "Yes" or "No" and QSSTRESC = "Y" or "N". If QSORRES = "Yes", then descriptions are represented in items QSTESTCD = "CSS0101A" - "CSS0105A". QSSTRESN is null for these items.
- The second section "INTENSITY OF IDEATION" contains 6 items (QSTESTCD = "CSS0106" - "CSS0111") rating the most severe ideation with responses represented with a numeric score (either "0-5" or "1-5") and associated descriptive text. If "Most Severe Ideation" (QSTESTCD = "CSS0106") is present, "Description of Ideation" (QSTESTCD = "CSS0106A") is collected as free text. For this section of the C-SSRS BASELINE, QSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.
- The third section, "SUICIDAL BEHAVIOR" contains 6 items (QSTESTCD = "CSS0112", "CSS0114", "CSS0115", "CSS0117", "CSS0119", and "CSS0120") with QSORRES = "Yes" or "No" and QSSTRESC = "Y" or "N". If QSORRES = "Yes", then descriptions are represented in items QSTESTCD = "CSS0113A", "CSS0116A", "CSS0118A", and "CSS0119A". QSSTRESN is null for these items. A "Total # of Attempts" (QSTESTCD = "CSS0113"), "Total # of interrupted" (QSTESTCD = "CSS0116") and "Total # of aborted" (QSTESTCD = "CSS0118) is collected in QSORRES. "Answer for Actual Attempts Only" contains "Most Recent Attempt Date" (CSS0121A), "Most Lethal Attempt Date" (QSTESTCD = "CSS0122A"), and "Initial/First Attempt Date" (CSS0123A) collected in QSORRES. "Actual Lethality/Medical Damage" for "Most Recent Attempt", "Most Lethal Attempt" and "Initial/First Attempt" (QSTESTCD = "CSS0121B", "CSS0122B", and "CSS0123B") and "Potential Lethality" (QSTESTCD = "CSS0121C", "CSS0122C", and "CSS0123C") are represented with a numeric score (either "0-5" or "0-2") and descriptive text. For this section of the C-SSRS BASELINE, QSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN.
- The time period of evaluation for the C-SSRS BASELINE is populated in the QSEVINTX field as an evaluation interval text value, since it cannot be precisely described as an ISO 8601 duration. The evaluation interval for the C-SSRS BASELINE is "Lifetime: Time He/She Felt Most Suicidal" (QSEVINTX = "LIFETIME").
- Items are divided into 3 subcategories represented in QSSCAT: "SUICIDAL IDEATION", "INTENSITY OF IDEATION" and "SUICIDAL BEHAVIOR".
- Some items on the C-SSRS BASELINE may be not done due to conditional branching. Items determined for conditional branching in the C-SSRS BASELINE are as follows:
- If QSTESTCD = "CSS0101" and "CSS0102" have QSORRES = "No", then the logic branches to QSTESTCD = "CSS0112" and QSTESTCD = "CSS0103" - "CSS0111" will not be done.
- Items QSTESTCD = "CSS0101A" - "CSS0105A" are only completed when the response to the preceding items (QSTESTCD = "CSS0101" - "CSS0105") is "Yes"; otherwise they are not done.
- If QSTESTCD = "CSS0112" has QSORRES = "No", then the logic branches to QSTESTCD = "CSS0114" and QSTESTCD = "CSS0113", "CSS0113A", "CSS0121A", "CSS0121B", "CSS0121C", "CSS0122A", "CSS0122B", "CSS0122C", and "CSS0123A", "CSS0123B", "CSS0123C", will not be done.
- If QSTESTCD = "CSS0115" has QSORRES = "No", then the logic branches to QSTESTCD = "CSS0117" and QSTESTCD = "CSS0116" and "CSS0116A" will not be done.
- If QSTESTCD = "CSS0117" has QSORRES = "No", then the logic branches to QSTESTCD = "CSS0119" and QSTESTCD = "CSS0118" and "CSS0118A" will not be done.
- If QSTESTCD = "CSS0119" has QSORRES = "No", then the logic branches to QSTESTCD = "CSS0120" and QSTESTCD = "CSS0119A" will not be done.
- If QSTESTCD = "CSS0121B", "CSS0122B", and "CSS0123B" have QSORRES = "1", "2", "3", "4", or "5", then QSTESTCD = "CSS0121C", "CSS0122C", and "CSS0123C" will not be done.
A derived record is created and a QS supplemental qualifier variable is used to indicate an item was conditionally branched. When an item is not done due to conditional branching, it is represented as follows:
QSDRVFL = "Y".
QNAM = “QSCBRFL”, QLABEL = “Conditional Branched Item Indicator “, QVAL = “Y”. (This is a QS supplemental qualifier variable.)
QSSTAT = "NOT DONE", and QSREASND is missing
- QSORRES, QSSTRESC and QSSTRESN are set to null (missing)
- Records are created in qs.xpt for every item on the sponsor's version of the instrument.
- For items not done due to conditional branching, refer to assumptions 4 and 5.
- In the unexpected situation where the reason is unknown, then QSORRES, QSSTRESC and QSSTRESN are all missing, QSSTAT = "NOT DONE", and QSREASND is missing.
Some responses to the C-SSRS SINCE LAST VISIT items exceeded the 200-character limit for the QSORRES variable and needed to be reduced to fewer than 200 characters. Section 4, SDTM Mapping Strategy, indicates which item responses were revised in order to fit the 200-character limit.
Terminology
QSCAT, QSTESTCD, and QSTEST values are included in CDISC Controlled Terminology.
A full list of value sets for the qualifier, timing, and result fields is provided in Section 4, SDTM Mapping Strategy.
3.2 Example for the C-SSRS BASELINE QS Domain Model
The C-SSRS BASELINE example below shows the terminology used to implement the instrument in the QS domain. This example shows the data for 1 subject collected at the baseline visit and another subject at baseline and visit 2 for the C-SSRS BASELINE instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCAT. All original results, matching the CRF item response text, are represented in QSORRES. This result is then represented as a standard numeric score in QSSTRESN and as a standard character representation in QSSTRESC. When a result is character only, the result is transformed into the standard character representation in QSSTRESC and QSSTRESN is null.
The table represents the items from the C-SSRS BASELINE instrument.
Dataset Wrapper Debug Message
Please add a row column to your dataset.
The suppqs dataset shows the items in the qs dataset which have assigned responses (QSDRVFL = "Y") due to conditional branching.
The following is for illustrative purposes and would not really be included for the IDS-SR instrument in this template. It provides an example of what would need to be included if the instrument required supplemental qualifiers (see Section 5 Supplemental Qualifier Name Codes):
Text that would remain unchanged has been left in black:
The evaluation interval text value for data collection needs to be populated in SUPPQS as follows. The standard terminology for QNAM and QLABEL are listed below.
STUDYID | RDOMAIN | USUBJID | IDVAR | IDVARVAL | QNAM | QLABEL | QVAL | QORIG |
---|---|---|---|---|---|---|---|---|
STUDYX | QS | P0001 | QSSEQ | Sequence number corresponding to row of qs.xpt that supplemental qualifier is needed for (e.g., 8) | Appropriate variable name to provide more information about data in qs.xpt, no more than 8 characters long (e.g., CONTACT). | Label for QNAM (e.g., Contact Type) | Value of QNAM variable ( e.g., SUBJECT VISIT) | CRF |
4 SDTM Mapping Strategy
This section is used for reference regarding the CRF data capture and to understand the alignment of the instrument to the SDTM QS domain. It also provides guidance on how the result variables (QSORRES, QSSTRESC, and QSSTRESN) should be populated.
QSSCAT alignment with QSTESTCD
As stated in Section 3.1 assumptions, items on the C-SSRS BASELINE are grouped into subcategories. The table below includes the subcategory names along with the applicable item numbers for each category. The values of the subcategories are used to populate QSSCAT and are annotated on the CRF.

5 Supplemental Qualifier Name Codes
The instrument used as an example in this template did not require supplemental qualifiers, but this section has been included to provide guidance on those instruments which do require supplemental qualifiers. (Many instruments do not require it.) Text that always will be in the section when it is included has been left black.
Additional rows will be required in the suppqs.xpt dataset for each supplemental qualifier needed.
Remove Section 5 if it does not apply to the new instrument.
The following table contains additional standard name codes for use in the Supplement Qualifiers for Questionnaires (SUPPQS) special purpose dataset.
QNAM | QLABEL | QVAL |
---|---|---|
QSCBRFL | Conditional Branching Item Indicator | Y |
